Mouser staff had been inspired by an installation of our Interactive LED Panels to create something interactive that they could show off at Engineers Week at the Fort Worth Museum of Science and History. They used the Octolively as the basis for their project, and the kids loved it of course.
For trade shows, they built up a display with a mix of blue and white LEDs to show off the Mouser “M”. Based on the foot traffic it got while I was at the booth, it is quite popular.
They made some minor changes from our original Octolively design and used different connector types to highlight Mouser’s product lines. The heart of the project is still the 40-pin DIP ATmega164P (perhaps anomalous at an ARM conference) running our Octolively code, which gave the Mouser folks a chance to play with some microcontroller programming.
It’s always exciting to see a derivative of one of our projects in the wild. Thanks to the Mouser folks for sharing their project story and sending the museum picture for us to share.

Ken Shirriff has written an excellent exploration of the 741 op-amp, including decapping a metal can package AD741. There’s a very cool interactive viewer so that you can click on the components in the schematic or on the picture of the die to see what each one is and does.
…The 25pF capacitor in the 741 has a very small value but takes up a large fraction of the chip’s area. You can see the capacitor in the middle of the die photo; it is the largest structure on the chip. …
Our very own XL741 is referenced in the footnotes, too.
You’re invited to our annual open house!
